they have already been here....maybe still are...government has known for a long time!! Disclosure coming soon!! They haven't been a risk so far !! I think we are a bigger risk than they are!!

Disclosure?

Yeah, any day now isn't it.

Been hearing that crap for over 20 years. You will forgive me if I do not hold my breath.

Things are what they are. - MeReality can't be debunked. That's the beauty of it. - CapeoIf I have seen further it is by standing on the shoulders of giants. - Sir Isaac NewtonLet me repeat the lesson learned from the Sturrock scientific review panel: Pack up your old data and forget it. Ufology needs new data, new cases, new rigorous and scientific methodologies if it hopes ever to get out of its pit. - Ed StewartYoutube is the last refuge of the ignorant and is more often used for disinformation than genuine research. There is a REASON for PEER REVIEW... - ChrlzsNothing is inexplicable, just unexplained. - Dr Who

Do you feel these people have come up with reasoning, or do they have an anti alien agenda?

I'm not sure that either of those men's opinions tell us much about the bigger question, beyond giving their individual opinions. If life has no other option then to come into existence through the natural paths of science (which I believe, as apposed to any divine question) then the lack of evidence to suggest such, against the sextrillions amounts of stars, only reminds us that we have merely peaked around the curtain so far, it doesn't tell us anything about the likely hood of finding such evidence. (drakes equation is even less convincing, it would have been easier if he had just written "my equation is a whole lot of if's, buts and maybe's" )

"Equipped with his five senses, man explores the universe around him and calls the adventure Science". ~ Edwin Powell Hubble

It might be but also on the other way around, I'm not sure if they can adopt to Earth's natural condition. There are many living organisms here, a single cell organism can be a threat to them, a simple flu can be a threat to them. An alien is an alien, they are alien for us and so we are alien for them.

I'm shocked to have read sevral posters who still have the out-dated view that there would be extreme panic and disorder!

Seriously?!

Most of the educated world expects there to be life and wouldn't be at all shocked if it were discovered. Pleasantly surprised at the timing, yes, but panic? No.

Every new generation will have seen more sci-fi than the one before it and also will have more space exploration available to it....
What I am trying to say (badly) is that each next generation will be less shocked than the one before, if we find alien life....

I read an SF short story in a pulp magazine a long time ago about the first trip to Mars (before we knew the planet's harsh nature) where there were on board an atheist and a Jesuit. Much of the trip consisted of discussion between the two as to what would happen if they found anybody there, and the Jesuit's view was that first he would have to determine if they had souls, and, if so, if they were under original sin or not, and if they were, he would need to begin to convert them. The atheist, of course, rejected this as nonsense and that they should be left to whatever religion or non-religion they already had.

Well they arrived and walked into a dusty little village, and all the people gathered around as they went in, and soon a leader appeared and walked up to them and bowed and said, "There is no God but Allah and Mohammad is his prophet."

Besides the catholic church have already made a statement that the discovery of advanced life would NOT intefer with scripture or their beliefs

Oh but it would whether they say so or not. If all sorts of life forms were out there and none of them were Catholic, it would seem odd. If on the other hand they were all Catholic then the rest of us would have to do some rethinking.

Do you feel these people have come up with reasoning, or do they have an anti alien agenda?

We are told about discoveries all the time, Try the papers.

Criticism of the Drake equation follows mostly from the observation that several terms in the equation are largely or entirely based on conjecture. Thus the equation cannot be used to draw firm conclusions of any kind. As Michael Crichton, a science fiction author, stated in a 2003 lecture at Caltech:

The problem, of course, is that none of the terms can be known, and most cannot even be estimated. The only way to work the equation is to fill in with guesses. [...] As a result, the Drake equation can have any value from "billions and billions" to zero. An expression that can mean anything means nothing. Speaking precisely, the Drake equation is literally meaningless...

Another objection is that the very form of the Drake equation assumes that civilizations arise and then die out within their original solar systems. If interstellar colonization is possible, then this assumption is invalid, and the equations of population dynamics would apply instead.

One reply to such criticisms is that even though the Drake equation currently involves speculation about unmeasured parameters,it was not meant to be science, but intended as a way to stimulate dialogue on these topics. Then the focus becomes how to proceed experimentally. Indeed, Drake originally formulated the equation merely as an agenda for discussion at the Green Bank conference.

It's nonsense and arrogance that make some people think that we are alone in te universe. Religions are based on the "fact" that we are unique in the universe. How this was determined probably gets back to the human race being "superior" to other life on Earth and elsewhere.

Finding life somewhere else is one thing. Having the life visit is another.
